Situated in the Parco Scientifico del Tecnopolo di Castel Romano, Plaisant offers a complete scientific and technical support for research in the biomedical field, when purchasers were supporting the companies and the institutes dedicating their adequate structure or that of a know-how specialised in the carrying out of some phases of experimentation.



First steps in the biomedical field

The company is born and, in little time, it plays a protagonist role in the field of biomedical research, as a breeder and specialised supplier of rodents both inbred and outbred.

After a period of planning, study and specialisation with renowned European Institutes of Research, Plaisant successfully proceeded with their breeding structure, importing colonies of foundation animals (ZFV, Hannover) and started to produce selected animals of high quality.

TESTIMONIALSWhat Clients say about us

We have worked with Plaisant since 2015 on essential preclinical studies for the development of our vaccines. We, from our first interaction, appreciated the great professionalism and preparation of the whole staff across different roles and functions. The service that Plaisant offers is not only excellent on the question of animal wellbeing, and of the planning and execution of the procedures. We have been able to really benefit from the fundamental support offered in phases of drafting and approval of the Ministerial Authorisations, as well as the training to new staff who are to be inserted in the experimentation. All of it managed with remarkable competence and flexibility that prove to be precious for those concerned with preclinical research in Italy.
Stefania Capone
In Castel Romano, Takis and Plaisant have collaborated for the past 13 years and the two companies have developed the perfect synergy. The seekers and technicians of Plaisant always find the best solution for any technical questions and provide great support of the Scientific Projects. I recommend Plaisant as an ideal partner to carry preclinical activities out and to reach results of high quality in an effective and fast way.
Luigi Aurisicchio
Nouscom has benefited from the service of stalling managed by Plaisant for years. The stalling is well organised and functional; the technical staff is suitably formed, educated, and very available for any queries. The daily interactions between ourselves and the technical staff of the Plaisant stalling ensures a serene environment, limiting any potentially stressful situations to the animals and guaranteeing the constant monitoring of the state of well being of the animals being experimented on. All of this guarantees a reliable and reproducible execution of the experiments, which is a fundamental aspect for scientific research.
